Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542754, here are decompositions:

167 + 31542587 = 31542754
317 + 31542437 = 31542754
431 + 31542323 = 31542754
521 + 31542233 = 31542754
557 + 31542197 = 31542754
641 + 31542113 = 31542754
743 + 31542011 = 31542754
773 + 31541981 = 31542754

Showing the first eight; more decompositions exist.
